and if you're mainly interested in backup, you could (further) encrypt your secstore's files with a non-trivial key before sending them to 9grid's secstore, then decrypt them with that key if you ever had to restore them. of course, in that case using 9grid's secstore on-line directly would require the client to know to use the extra key. another variant would be to split the material in some way across several secstores operated by different people
